Since my first metal show in 2005, I've seen Amon Amarth, Behemoth, Children of Bodom, Lamb of God, and (unfortunately) Trivium four times each. Oh, hey, neat, never noticed that - three of those bands (Amon Amarth, Trivium, and CoB) WERE the aforementioned first metal show...

CoB will be 5 times next month, and Ensiferum should be 4x in November.
